Facade sealing for businesses in Theale

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Cost factors for facade joints

Quotes vary with the job. It mainly depends on:

  • Location, for remote and island sites
  • Quantities, in metres or numbers
  • The size and state of each joint
  • Any access equipment needed

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Clear photographs of the problem areas
  • Access details, including height
  • Where the site is, with the postcode
  • Whether an asbestos survey exists

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

How we handle facade sealing in Theale

We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds, using sealants classified for facade or glazing use. We work on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints, and the usual reasons a site gets in touch are previous reseals run over old sealant and weathered joints at frame-to-structure perimeters. Most enquiries from Theale start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

On a small site around Theale, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or send photos by email and we will come back to it.

Surface by surface

Coping and flashing joints

Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Joints whose design needs changing by the specifier
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Specialist high-level access methods

If you are not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer.

Where we work in Theale

  • Perimeter joints where frames meet the structure
  • Window and door perimeters
  • Shopfront frames
  • Stone and brick facade joints
  • Coping and flashing joints
  • Cladding panel joints

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep sills, gutters and drainage paths clear
  • Plan facade sealing alongside redecoration
  • Confirm the survey covers external sealants in older buildings
  • Record the product and colour used on each elevation

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly using a matching sealant.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking anything from a single day to several weeks, depending on joint lengths, access and the weather. Work in places the size of Theale is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

Preparing the site

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Facades, frames and programmes in Theale

Theale sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. There are a number of hotels within about 2 miles of Theale. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.

Projects at colleges like Integration College (1.2 miles north-east of Theale) tend to run to term dates, so the mastic is planned tightly. New units and refits on sites such as Chiltern Enterprise Centre, less than half a mile south-east of Theale, need their panel and perimeter joints sealed to the specification. Work at a hotel such as Old Lamb Hotel, under half a mile to the west of Theale, tends to be programmed around bookings, mastic included.

Theale is about 4 miles west of Reading, in West Berkshire. We cover Theale and the rest of West Berkshire, with the same fixed quotes and 12-month guarantee as everywhere else. Theale is one of 140 places in West Berkshire on our list for facade joints.

Business premises anywhere in RG7 are within our area. If your site is on Station Road, High Street and Bath Road or close by, we can quote for facade joints. Sites close to Theale are covered too, including Sheffield Bottom (1 mile south-east), Englefield (1 mile north-west), Calcot (1 mile east), Beansheaf Farm (1 mile east) and Trash Green (2 miles south-east). Bigger towns within reach include Newbury (11 miles west), Thatcham (8 miles west), Burghfield Common (3 miles south), Speenhamland (11 miles west), Shaw (10 miles west) and Burghfield Hill (3 miles south).

Questions we’re asked in Theale

Do you take on work at healthcare sites like Prospect Park Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Will you take on work at estates like Chiltern Enterprise Centre, close to Theale?

Yes. Our area takes in Theale and its surroundings, with estates and business parks such as Chiltern Enterprise Centre included. Photos and a short description are enough for a first look.

Is colour matching possible?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Can staff carry on working while you’re here?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Do you cover Theale?

Yes. Theale falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or email the details over.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Can you find out why a window is leaking?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Work for main contractors and building owners

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Theale can form part of a wider programme across West Berkshire.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
